Few things ruin a relaxing swim quite like grubby paving or slippery tiles. A clean poolside feels fresher, safer, and more welcoming.
With the right kit and a little know-how, pressure cleaning can keep it that way, without causing damage.
Why Pressure Cleaning Works Wonders
Pressure cleaning stands out because it offers a powerful, targeted solution to outdoor grime that ordinary methods can’t match.
The high-velocity water stream physically lifts dirt, algae, mould, and surface contaminants from patios, pool surrounds, and paving, without the need for harsh scrubbing or repeated effort.
Unlike hoses or buckets, which tend to spread dirt rather than remove it, pressure washers cut through buildup by concentrating force in a narrow stream.
This makes them especially effective in areas that trap moisture and debris, like textured stone, ridged tiles, grout lines, or corners near drains. In just a few passes, they restore clarity and traction to surfaces that might otherwise stay slippery or stained.
Beyond that, pressure cleaning acts as a form of preventative care. Algae, mildew, and organic growth not only look unpleasant but can also degrade materials over time or create slip hazards.
Regular pressure washing keeps these issues in check, extending the lifespan of your poolside surfaces and helping them stay safe underfoot.
That said, not every surface is suited to high pressure. Materials like weathered wood, painted finishes, or old tile work may respond better to a softer approach.
Using too much force can wear away coatings, shift grout, or expose cracks, so careful judgement is key. Where needed, softer attachments or spray settings allow you to clean effectively without compromising the integrity of the material.
Choosing the Right Washer (and Why It Matters)
Picking the wrong pressure washer is a bit like trying to chop vegetables with a blunt knife. It’ll do the job eventually, but not without a lot of hassle.
To select the appropriate machine, the key things to check are the PSI (which tells you how powerful the water pressure is) and the litres per minute rating, which shows how much water it uses.
Higher PSI is ideal for blasting through stubborn grime on stone or paving slabs. For more delicate surfaces like older tiles or painted finishes, a lower PSI will clean effectively without causing damage.
The litres per minute figure gives you an idea of speed. More water means faster cleaning, but it also increases usage, so finding the right balance is important.
Furthermore, electric washers are lighter, quieter, and generally easier to use, making them perfect for smaller spaces or occasional use.
Petrol models offer more power, which is helpful for larger areas or really stubborn build-up, though they do require a bit more effort to handle.
It’s also worth investing in a few handy extras. An adjustable nozzle lets you change the spray pattern to suit the task. An extension wand can help you reach awkward spots without stretching or crouching.
And if you’re tackling tough dirt, a rotary brush attachment often lifts it far more gently than ramping up the pressure.
Before You Start: Stay Safe and Sound
Pressure washers aren’t toys. Before you power up, take a moment to run through the safety basics.
Start with your outfit: proper eye protection, durable gloves, and non-slip footwear. It might seem over the top, but a jet of water at full force can easily send grit flying or scrape skin.
Next, think about electricity. Use an outdoor socket with RCD protection, and make sure all connections are dry and safely away from puddles. Never trail a cable through standing water, and avoid extension leads unless they’re rated for outdoor use.
Finally, if you’re using any cleaning solution, read the label. Follow the instructions to the letter, and store anything hazardous well out of reach of kids or pets. Once you’re finished, dispose of leftover products properly. Never pour them down outdoor drains.
A Quick Prep Goes a Long Way
Don’t skip the prep! It’s the secret to a smooth, stress-free clean.
First, tidy the area. Remove anything loose: toys, plant pots, furniture, even cushions if they’re within reach of the spray. Sweep away dry leaves and dust to stop them from flying about or blocking the nozzle.
Lower the pool’s water level slightly if you think spray can bounce back in. Cover plants nearby with plastic sheeting or old towels to protect them from splashes and detergent.
If you can’t move your garden furniture, cover it too, as water and chemicals don’t mix well with rattan or wood. This stage takes just a few minutes but can save hours of extra cleaning and potential damage later.
How to Clean Like a Pro
Now for the fun bit. Hold the nozzle around 30 to 45 centimetres away from the surface. Too close and you’ll risk chipping it. Too far and you won’t clean anything.
Work in smooth, overlapping lines. It’s a bit like mowing the lawn—steady, deliberate passes give the best results. Don’t rush or dart back and forth.
For stubborn patches, apply a cleaning solution and leave it to soak for a few minutes before rinsing. Just make sure you rinse thoroughly afterwards. If dirt remains, a rotary brush can help lift it without needing to blast at full force.
Try to avoid spraying directly into tile joints or grouting, as this can loosen or damage them over time.
Aftercare: The Bit Everyone Forgets
Once you’re done, resist the urge to pack everything away immediately. Give your washer a little love.
Flush the machine to remove any leftover detergent. Dry off the outside and coil up the hose loosely. Store everything somewhere dry and sheltered—damp sheds and tangled cables are a recipe for broken kit.
Take a quick walk around the cleaned area. Look for cracked tiles, loose edges, or anything improper now that everything’s spotless. Spotting small issues now can stop them from turning into expensive fixes later.
Remember that consistent care helps your equipment last longer and keeps your poolside looking good between cleans.
Be Kind to the Planet While You Clean
Pressure cleaning can be surprisingly eco-friendly if used thoughtfully. Unlike scrubbing with a hose and bucket, you can clean more surface in less time, using less water overall. But it still pays to be mindful.
Focus only on areas that actually need it. Choose lower pressure settings and use nozzles designed to conserve water. Better yet, consider collecting rainwater to use for outdoor jobs.
Stick with biodegradable, phosphate-free cleaning products. Many traditional detergents contain ingredients that damage soil, harm insects, or pollute water systems. Eco-labelled options are widely available and just as effective.
For light messes or spot treatments, a stiff broom and warm soapy water often do the trick, and not a drop is wasted.
Conclusion
Pressure cleaning doesn’t just scrub your paving—it gives the whole space a lift. There’s a quiet satisfaction in watching the dirt peel away, one strip at a time.
And when the sun hits those newly washed tiles? It feels like the start of summer.
